specification.

A of the ovenstructure and inspected without' My invention relates to improvements in as furnaces or coke ovens havin vertical heating flues; and the objects o my 1mprovements are, rst, to provide a more efficient and simpler means ttoryheating the air for combustion; and second, to provide means for regulatin the supply of air and gasi to each heating ue.\ `According to the 'present invention the heating ilues have inserted tubes or the like made of fire clay, iii-e brick or other refractory material, by whichthe air is conducted to the places of combustion, o n its -wa through said tubes becoming highlyheate The air supply and heating tubes.. form separate, independent bodies. with respect to the oven structure and can furthermore in case of their becoming defective be readily exchanged through openings provided for this purpose in the oven structure. The air inlets of said tubes can be separately and individually regulated b nozzles, slides or the like, which are ikewise accessible through the before mentioned openings.

The gas for combustion is distributed over the oven walls in the usual manner by pipes or the like, provided with nozzles or burners. In order to allow an easy control and regulation of the nozzles or burners without discomfort to the workmen, I ropose to connect the gas distributing bo ies to the gasmain by flexible tubes, such as rubber oses or the like, so that said supply distributing bodies may readily be drawn out `von lines 3 4' of Fig. 1; and Fig. 3 is a detailed sectional view showing a special construction and arrangement of the air supply and heating tubes by which same can also be used as a means for regulating the gas su fil to eachheating flue. y

In t e orizontal oven selected by the way of example the coking chambers and the heating walls b are arranged side by side' in the usual manner. The heating iiues of the ovenvwalls .have inserted these air supplyand heating tubes-c, `which are provided with air outlets d at their lower end. The upper ends of said tubes are furnished with nozzles e, which are interchangeable through openings f in the oven structure. These openings-also allow the whole tubes to be drawn out of the heating ues and repaired or new ones inserted if such should become necessary.

Theiiiif enters the o'veii structure 'through ropenings q and before enterin the tubes 'o is subjected to a'- reliminary veatingiin 'a system of iiues or c annels 'h arranged above the oven chambers.

The gas forcombustion `is conveyed-to and distributed over the heatin fines by the distributing bodies z' of Whic there are two for each oven wall.' They are connected to the gas main 7: by rubber hoses l. A cock m serves to regulate the supply of gas to each distributing body, while the amount of -gas supplied to each heating fiue can be regulated after the body i is drawn out of the oven structure bv exchanging the nozzles or burners.

Thevproducts of combustion after leavin the heating iues at the top, pass throng the ,upper horizontalflue n and down through the four center {iues to the main conduit o. The iniiuence of the chimney draft on each oven walll can be regulatedI by the damper p.

The construction and arrangement of theV air supply and heating tube as shown def tailed in Fig. 3 has for its purpose to serve also asa means for regulating the supply of as to the heatin an heating tube g in this case is provi on its upper end with projections Ahaving inclined faces r, which rest on similary projections of the oven brick work. The lower end of the tube is tapered, and projects into the ta ered gas inlet s. Throu h turning the tullie, which can be eiected om above the same is raised or lowered, thereby increasing 'or decreasing the eiectual cross section of the gas inlet s.

Having now described flue. The air supply and ascertained the 116 nature of my saidl'invention, I declare that `what I claim is 1. In a battery of as furnaces or coke ovens having vertical eating fines, air supply pipes in said 'lues, terminatin at or near the lower ends of the latter, an forming separate and independent bodies with respect to the oven structure.

2. In a battery of as furnaces or coke ovens having vertical eating lues, air supply pipes in said iiues, terminatin at or nea-r the lower ends of the latter, an forming separateand independent bodies with respect to the oven structure, and openings in the upper part of the ovenlstructure so as to erm it access to aforesaid pipes.

3. fn a battery of gas furnaces or coke ovens having vertical heating fines, air supply pipes in said flues, terminating at or near the lower ends of the latter, and forming `separate and independent bodies with respect to the oven structure, and air passages in the upper part of the oven structure, communicating with the upper ends of aforesaid pipes.

4. In a battery of 'as furnaces or coke ovens having vertical eating fines, air sup- 5. In a battery of gas furnaces or cokeA ovenshaving vertical heating Hnos, air supply plpes 1n rsaid fil-ies, termmatmg at or near the lower ends of the latter, and forming separate and independent bodies with respect to the oven structure, openings in 4the upper part of theloven structure, so as to permit access to said pipes, and gas snpply passages communicating with the lower ends of said vertical heating filles, and controllable by means of aforesaid air supply pipes. y
